AIR-NOZZLE FOR TRACK-SANDERS.

Specification of Letters Patent.

Patented Oct. 1, 1918.

Application filed January 8, 1918. Serial No. 210,922.

To all whom 'it may concern.'

Be it known that I, ELMER E. BRADLEY', a citizen of the United States, residing at Clinton, in the county of Clinton and State of Iowa, have invented certain new and useful Improvements in Air-Nozzles for Track-Sanders, of which, the following is a specification.

This invention relates to air nozzles for track sanders, and aims primarily to sini* plify and improve the construction and op eration of devices of this character as well as to increase the efficiency of the same.

A further object of' the invention is to provide a` nozzle for use in connection with track Sanders which is, constructed in such manner as to obviate the possibility of the air discharge ports becoming sealed or clogged with sand or dust, thereby obviating the possibility of the sanding device being rendered inoperative.

A still further object is to provide an in jeetor or nozzle of the character mentioned which is adaptable to practically all types of fluid pressure sanding devices new i n use. which is composed of but few simple, inex pensive and easily assembled parts, which capable of being readily detached from the sanding apparatus for the purpose of cleaning or repairing, which may be readily as sembled or dismantled without the aid oi' special skill or tools, and which will enable the sanding apparatus to be immediateliy responsive upon the application of fluid pressure.

With these objects in view, together with others which will appear as the description roceeds, the invention resides in the novel ormation, combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the claims.

In the drawings c Figure 1 is a longitudinal sectional view taken through a track sanding air nozzle oi my invention,

Fi 2 is a rear elevation of nozz e,

Fig. 3 is an enlarged side elevation of the end of the improved nozzle, and

Fig. 4 is a sectional view taken substantially upon line 4 4 of Fig. 3.

Referring now more particularly to the drawings, 5 indicates the casing for the injector or nozzle, having reduced nipples 6 the improved and 7 at its ends.i These nipples are both provided upon their exterior surfaces with screw threads as shown, and the bore of the nipple 7 is internally threaded.

The improved air nozzle is indicated generally at 8, and comprises an elongated shank having a relatively large central'bore 9 extending throughout substantially the entire length thereof. The rear end of this nozzle is enlarged and is exteriorly threaded so as to permit of the same being screwed into the bore of the nipple 7 and a jam nut 10 is threaded upon the said rear end of the nozzle shank lo hold the latter in proper adjusted position in its retaining nipple. The forward end of the nozzle is provided with a heed 11, the said head being pointed at its forward end, und provides an annular rearwardly facing wall or shoulder 12 at its rear end. A relatively small port or opening 13 extends from the point of the head 11 rearwardly and communicates at its rear end with the larger bore 9 of the nipple. The head 11 is also provided with a plurality of angular-ly disposed ports 14, which communicate at their inner ends with thelarger part of the bore 9, and extend rearwardly and open out in the rearwardly facing wall or shoulder 12 of the said head.

To enable the improved injector or nozzle to be applied to the sanding apparatus of a locomotive, an internally threaded sleeve 15 is provided, the said sleeve being pro' vided at one end with an annular flange 16 adapted to be engaged by and firmly held in position uponv the nipple 6 by a coupling nut 17. It will be understood thatl the threaded end of the 'sleeve 15`may be applied to the pipe or any other part of the sanding apparatus. It will also be observed that the bore of the sleeve 15 is reduced at its rear end, and the angularly inclined walls of lthe bore approaching the reduced end of the said nip )le will assist in preventin sand or dust wor ring back into the chamer of the casing 5.

In operation, the sleeve 15 is coupled to the sand box or distributing chamber of the sanding apparatus, and an air pipe may be attached to the nipple 7. Air entering the bore 9 of the nipple will escape therefrom through the forwardly extending opening 13 of the nipple as well as through the an larly and rearwardly disposed ports 14. he air will then escape from the nozzle chamber through the sleeve 15, and will force the sand of the apparatus through the distributlos ing pipe. By arranging the nozzlel 8 in tho manner mentioned, it 1g obvious tlm@ the chamber Within which themnozzlo 'iS positioned may contain a oonsidemhleanloum of sand or dust Without in any Way affecting @Qgpeggtio ofghgsgil nozzle.
